. SHADE-HOLDER.

Specification of Letters Patent.

Application filed Harchfl, 1918. Serial No. 221,483.

To all whom it may concern:

Be it known that I, ARTHUR J. TIZLEY, a citizen of the United States ofAmerica, residing in the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a certain new anduseful Improvement in Shade-Holders, of which the following is aspecification;

My inventionrelates to shade-holders and partlcularly 'to a support forshades of the inverted globe type, the object of my invention being toimprove the construction shown in the Evans et al. Patent 1,192,049, byrendering the locking device thereof automatic.

In the accompanying drawing,

Figure 1 is a section through a fixture showing my invention applied tothe globe holder in one form;

Fig. 2 is a plan of the globe holder detached;

Fig. 3 is a broken plan of one of the supportin arms, showing thesupporting finger thereo in position to permit the adjustment of theglobe;

Fig. 4 is a side elevation thereof, showing the locking sleeve insection. ,4

In the shade holder shown in the Evans patent above mentioned, one ofthe support: ing arms is made in two parts plvoted together and normallyheld in alinement by a locking sleeve. The latter, however, is looseupon the arm and must be moved positively in both directions first toreleasethe sections to permit them to pivot with relation to each other,and thereafter again to lock the same in alinement. Moreover, when theparts are released, the globe-engaging end or finger of the arm is freeto swing and does not maintain any precise relationship to the fixtureend of the arm, with the resultthat it is apt to get in the way duringthe adjustment of the globe on the support. By my present improvement, Iprovide the locking sleeve. with means for automatically returning it'tolocking position when the globe-engaging finger is swung up intooperative position, and, at the same time, mamtam the finger inpredetermined out-of-the-way position during the adjustment of the globeon the holder.

While the globe holder may ap lied to fixtures of various sorts and maye supported in any suitable way, I have here in- (icated it a plied to alamp socket 10, on the casing of w ch is' secured an ordinary globe rodsfixedly secured at their upper endsto a channel ring 18 adapted to beinserted wi Patented July 30, 1918.

in the skirt of the shade holder 11 and engaged by the set screws 12 tohold it in position. The two arms 15 and 16 are rigid throughout theirlength. The arm 17 is'di-' 'vided, and the outer free end thereof formsa globe-engaging finger 19, pivoted thereto at 20. A lap joint betweenthe sections of the arm is formed by cutting away the pivoted ends ofthe arm sections, and the end of the finger 19 is beveled at 21 topermit the finger to swing downward as indicated in Fig.

- 4, but forming a stop bearing against a simlar incline 22 on the fixedend 17 to prevent the upward swlng of the finger. 19 and halting thelatter when in alinement with the fixed end 17.

In order to hold the finger 19 in alinement wlth the fixed end of thearm 17, I pro-' vide a locking sleeve 23, sliding on the fixed portion17 of the arm and abutting at one end against the eads of the pivot pin20 which prevents t e sleeve from running down the finger 19. Thelocking sleeve 23 is of greater diameter than the arm 17 and forms ahousing for a coil spring '24:, one end of which is offset and passedinto a hole 25 in the arm 17 while the other end there-' of abutsagainst a shoulder 26 formed in any suitable way at the end of thesleeve adjacent the joint between the arm sections. The end of thesleeve is preferably rounded or beveled at 27 to facilitate theautomatic action of the locking sleeve when the finger 19 is swung upinto globe-engaging position.

The operation of the device is readily understood. Under normalconditions, the locking sleeve holds the finger 19 in alinement with thearm 17 as indicated in Figs. 7

only action engagement swing up the finger 19 into alinement With or theglobe by the holder is to the arm 1?. 9n its upward movement, thebeveled end 21 of the finger l9 bears against the bevel 27 on the-locking sleeve 23 and forces the latter up the arm 17 against theaction of its spring 2d. As soon as the finger 19 comes in alinementwith the arm 17, the sleeve 23 is automatically returned by its spring2% into locking engagement there with and rests against the heads of thepivot pin 20. The finger 19 is thus held rigidly in supporting position.

The improvement thus provided does not alter in any Way theappearance-of the support, and has the advantages above pointed out, inaddition to those disclosed in the Evans patent. The manner in which thearm is secured to its supporting ring is immaterial, as is also thecontour of the arm and the shape of the supporting finger, and I do notlimit my claim of invention to the precise form of constructionillustrated.

claim:

1. In a shade holder an arm, a shade-engaging finger pivoted thereto butmovable to out-of-the-Way position during the adjustment of the shade onthe holder, and a spring pressed locking member holding said finger inboth positions, together with means automatically displacing saidlocking device as the finger is moved to shade-engaging position butthereafter releasing said locking device to permit it to return underthe acreveal 'out-of-the-way position during tion of its spring tolocking positi and thus hold the finger in shade-engaging position.

2. in a shade holder a supporting arm having jointed theretoshade-engaging finger, in combination with a displaceable spring pressedlocking mber said arm and finger to d latter in normal shade-engagingreleasing said locking me m reaches its normal positio tether o theautomatic return of said member looking position under the action ofspring.

3. In a shade holder an arm, a shade-engaging finger pivoted thereto buovable to la r.

ment of the shade holder, a locking sew. mounted on said arm andengaging said finger to hold it normally in looking" position, togetherwith a cam lug on said finger engaging said sleeve to displace the sameout of obstructing position as the finger is brought into its normalposition.

i. In a shade holder an arm having a shade-engaging finger pivotedthereto, in combination with a spring pressed locking sleeve mounted onsaid arm and engaging said finger to hold the latter in normal positionwith relation to the arm, together with a cam lug on said fingerautomatically displacing said sleeve out of obstructing position as thefinger is moved into its normal shade-engaging position.

In testimony whereof I have signed my name to this specification.
